Sample Text	We evaluate the electromagnetic Ξcγ→Ξc ′ transition on 2+1 flavor lattices corresponding to a pion mass of ∼156 MeV. We extract the magnetic Sachs and Pauli form factors which give the Ξc–Ξc ′ transition magnetic moment and the decay widths of Ξc ′ baryons. We did not find a signal for the magnetic form factor of the neutral transition Ξc 0γ→Ξc ′0, which is suppressed by the U-spin flavor symmetry. As a byproduct, we extract the magnetic form factors and the magnetic moments of Ξc and Ξc ′ baryons, which give an insight to the dynamics of u/d, s and c quarks having masses at different scales.
